Not everyone's work history looks the same. Some people worked part-time for most of their adult lives. Others were self-employed, worked seasonally, or took long breaks from the workforce. When a disability strikes and income disappears, those workers often assume they're automatically disqualified from Social Security Disability Insurance (SSDI). That's a common misconception worth clearing up.
SSDI eligibility comes down to a system called work credits, and even part-time wages can count toward that total. The Massachusetts SSDI lawyers at Keefe Disability Law help clients sort through exactly these situations, determining eligibility, filing applications, and pursuing every available option when SSDI is unavailable or insufficient.
How SSDI Work Credits Actually Work
SSDI is funded through payroll taxes, and the Social Security Administration (SSA) tracks contributions through a work credit system. Job type matters less than most people think.
What Counts as a Work Credit
Credits are based on covered earnings reported to Social Security through payroll taxes or self-employment taxes, not on hours worked, job title, or how many quarters someone was employed. In 2026, a worker earns one credit for every $1,890 in covered earnings, up to a maximum of four credits per year (reached at $7,560). A person working part-time can earn all four credits in a single year once their reported earnings hit that threshold.
Self-employment income counts too, but only when net earnings are reported and self-employment taxes are paid. Someone who worked cash jobs, got paid off the books, or simply didn't file taxes likely won't receive credit for that work. This is especially important for gig workers, domestic workers, and anyone paid informally. Unreported income generally does not create SSDI credits, regardless of how hard or how long someone worked.
How Many Work Credits Do You Need?
Total work credit requirements depend on age at the time of disability, but the recent work test is equally important. It's not enough to have accumulated credits over a lifetime; a portion of them must have been earned in the years leading up to the disability.
Most applicants over 31 need a total of 40 credits, including 20 earned during the 10 years immediately before becoming disabled.
Workers disabled before age 31 face different calculations. SSA generally requires credits earned in at least half the quarters between age 21 and the onset of disability, with special minimum rules that vary by exact timing. It's also worth noting that meeting the work-credit requirements alone does not guarantee approval. Applicants must still satisfy Social Security's medical definition of disability, which is an entirely separate determination.
What Happens When You Don't Have Enough Credits
Not having enough work credits doesn't necessarily end the road. Supplemental Security Income (SSI) is a separate program that requires no work history at all. It's the most important alternative for people with little or no earnings record, and it's worth understanding early.
The Difference Between SSDI and SSI
SSDI is an earned benefit tied to Social Security contributions. SSI is needs-based: it's available to people who are disabled and have limited income and assets, regardless of work history.
To qualify, an individual generally cannot exceed $2,000 in countable assets ($3,000 for couples). Certain assets, including a primary residence and, in many cases, one vehicle, may not count toward that limit. SSI recipients in Massachusetts may also be able to access Medicaid/MassHealth coverage, though the connection between SSI and Medicaid can vary depending on individual circumstances.
Qualifying for Both SSI and SSDI
SSI may supplement a very low SSDI benefit depending on total countable income and household circumstances. The following situations often involve dual eligibility:
- Minimal work history with recent part-time employment. A small SSDI benefit may be supplemented by SSI when total income falls below program thresholds.
- Gaps in employment due to caregiving. Time away from the workforce to raise young children, for instance, doesn't erase past contributions, but it may create a recent-work problem.
- Self-employment with inconsistent or unreported income. Gaps in reported earnings can leave someone with fewer credits than expected.
- Young workers with early-onset disability. Lower credit requirements may still yield a modest SSDI benefit that SSI can supplement.
What to Do if You're Unsure Whether You Qualify
The most practical first step is checking your actual earnings record. Through a free My Social Security account, anyone can view their reported earnings history and estimated credits. Gaps, missing years, or lower-than-expected figures often surface there. Catching them early can make a real difference in how a claim is built.
From there, having an experienced disability attorney review the record helps clarify whether the total and recent work requirements are met, whether SSI is the better path, or whether both programs apply. Keefe Disability Law has served clients across Massachusetts, New Hampshire, and Rhode Island for over 30 years, handling the application process, medical documentation, and any hearings that follow. Our clients don't have to face an unfamiliar system alone.
